| The solid state and solution structures, photoluminescent properties, and the quenching event of ZnL with various nitro compounds will be discussed. This work is an effort toward understanding the relationship between structure and fluorescence of ZnL, and the dynamic quenching observed with nitro compounds, which are representative of explosives. Solid and solution state characterizations of varied ZnL(solvent) complexes are determined by X-ray crystallography, 1H-NMR and molecular weight determinations. In solution, the quantum yield and fluorescence wavelength are nearly insensitive to solvent; in contrast, the emission wavelength in the solid state varies for different ZnL(solvent) complexes. Nitroaromatics and 2,3-dimethyl-2,3-dinitrobutane (DMNB) are moderately efficient quenchers of ZnL*. |
